Application fled April it,

v is invention relates to shoe sole applying machines and has especialrelation to machines tor securing soles tn shoes hy the use oi cement.

u ohject oi the present invention is the provision out a mac t of theahove character wherehy the upper and the sole are pressed together in amanner to force air outward item the center heyond the edges ot thesole, and

in than avoid pockets, and consequently more securely attach the sole inposition.

Another ohject ot the inventio is the pro vision ot novel means torprovig a pneuntic support for e shoe during the sole attacg operationand tor holding said support in place so as to resist outward epreaegmovement, wherehy the sole will he held close contact with the upperthroughout its entire area and e tormation ol air ochets hetween thesole and upper will thus e prevented.

ether ohject ol the invention is the provision ot a achine otthe ahovecharacter which is simple in coruction, e ti cent in use, and hy meansot which a sole may he attached to a shoe in a relatively short time andwith a amount ot lahor.

With the shove and other ohjiects in view, e invention further includesthe tollowing novel teatures and details ot construction, tn

hereinafter more lully descrihed, illustrated in the accompanyingdrawings and pointed out in the appended clas.

Referring to the drawings in detail wherein like characters nitreterence denote corresponding parts, the reterence character 10indicates the hase oi the machine which may he of suitahle size andshape and trom which rise spaced standards ll. These standards support aher 12 at their upper ends so that ibis her is spaced ahove and parallelwith the ase.

Mounted upon the lease 10 are holders 1% which are designed tn receive apneumatic supporting element or hag lit, the latter heing designed tosuport the shoe while the sole is heing ap lied.

Any numer ot these holders 1% and hugs it may he provided, two heingshown, so that soles may he simultaneously applied to a pair ol shoesindicated at 15. The hags it are removahly positioned within the holdersand tor this purpose, one end wall ltd ot each ot the holders isremovahle. Headed studs lt' ertend "from the ends ot the holders and theremovahle ends it are provided with spaced slots 19 which receive theseheaded studs.

'lhe hags it are preterahly made ol leather and are shaped to centersuhstantially to the shape ot the holders. lnner ruhher hags or'hladders l9 are positioned within the leather hags it and are adaptedto he inflated through valves 90. The hags ll may he termed as shown inFigure 6 and laced as indicated at 21, so that they may he readilyopened and closed and the hladders renewed when desired.

y reference to lFigure lot the drawings it will he seen that the cornersor edges oil the hag are rounded and that the inner walls ot the holder13 curve inwardly at their upper edges and prevent spreag ol the hagwhen pressure is applied to its upper surtace.

The relerence character 29 indicates a pressure arm, one oil which isprovided lor each hag holden, flue end oi this pressure arm carries amemher 29 which is adapted to hear upon a last or tree 24. positionedwithin the shoe. 'lhreadedly engaging the other llti tltl

liti

end of the pressure arm 22 is a rod 25 whose lower end carries apressure foot 26 which is adapted to bear upon the upper of the shoe.The upper end of the rod 25 is provided with a squared extremity 27 tobe engaged by a suitable handle or tool.

Threadedly engaging the bar 12 are threaded shafts 28. One of theseshafts is provided for each bag holder and their lower ends engagerecesses or pockets 29 provided in the pressure arms 22. The upper endsof the shafts 28 are provided with squared portions 30 to be removablyengaged by a hand wheel 31.

By operating the shafts 28, pressure may be applied to the shoe and asthe latter is positioned upon the pneumatic supporting element or bag14, pressure will be applied centrally of the shoe outward due to thefact that the walls of the bag holder 13 confine the bag and resist itsspreading movement.

' This action will cause air between the upper and sole to be forcedoutward and thus eliminate the formation of air pockets.

Also mounted upon the base 10 between the standards 11 is a sole boardor sheld 32, upon which the shoe sole may be placed while beingroughened and prepared for cementing. A clamping screw 33 which isthreadedly mounted in a bar 34 serves to clamp the shoe sole in placeduring this operation. The screw 33 is provided with a squared tool orwheel receiving portion 35, whereby the screw may be adjusted.

The invention is susceptible of various changes in its form, proportionsand minor details of construction and the right is herein reserved tomake such changes as properly fall within the scope of the appendedclaims.

Having described the invention what is claimed-is .1. In a shoe soleapplying machine, a base, a bag holder mounted upon the base andincluding side and end walls, one of said walls being removable, apneumatic bag removably located within the holder with the upper face ofsaid bag exposed for engagement by the sole of a shoe, and means toapply downward pressure to the top of the shoe.

2. In a shoe sole applying machine, a base, a bag holder mounted uponthe base and including side and end walls having their inner facescurved inwardly at their upper edges, one of said walls being removable,a pneumatic bag removably fitted within the holder and having itsupperface exposed for engagement with the sole of a shoe, and means to applydownward pressure to the top of the shoe.
